Purchased at an estate sale on October 23, 2022 (alongside PS-6200, Radio Shack TRS-80 PC-4, Radio Shack TRS-80 Aviation, Sun Hemmi 341 3215, Texas Instruments SR-50A, Commodore SR4912, Texas Instruments TI-1025, Texas Instruments TI-32). I grabbed it quickly at the sale without looking too closely along with a couple other Radio Shack pocket PC things and didn't realise that it wasn't compatable with the PC-4 I bought there. Not too sure if it works as I don't have the right pocket PC to test it, but it is in very good condition.
